To Set Cruise Control

  2. Accelerate to the desired speed.
  3. Push the cruise control lever down and release it.
  4. Remove your foot from the accelerator pedal.

To Resume a Set Speed

Once cruise control has been set at a desired speed, the set speed is stored in the controllers memory. If the driver for any reason must apply the brake, cruise control will disengage. The cruise control may be reset in this manner, accelerate close to the desired speed (25 mph (40 km/h) or more, push up on the cruise control lever which operates the R/A switch (which stands for Resume/Accelerate) for about half a second. The vehicle will now accelerate to and resume the previously set speed. If either the ignition switch, Cancel switch or the cruise ON/OFF switch is turned off, you will erase the cruise control memory.

To Reduce Speed While Using Cruise Control

There are two ways to reduce your speed while using cruise control.

  1. Press and hold the cruise control lever down until you reach the lower speed you want. Then release it.
  2. To slow down incrementally, press the cruise control lever down for less than half a second. Each time you do this, the vehicle will slow down 1.6 km/h (1 mph).

To Increase Speed While Using Cruise Control

There are two ways to increase speed while using cruise control.

  1. Accelerate to the higher speed, push the cruise control lever up, then release the lever and the accelerator pedal. The cruise control will now maintain that the higher set speed.
  2. Once a set speed has been chosen, the driver can raise the cruise control lever engaging R/A, and hold it there until the new speed setting is reached then release the lever. To increase your speed incrementally, raise the cruise control lever for less than half a second and release it. Each time you do this, your vehicle will go 1.6 km/h (1 mph) faster.

The accelerate feature will only work after you have turned on the cruise control and push the SET button.

Passing Another Vehicle While Using Cruise Control

Use the accelerator pedal to increase your speed, once a safe distance past the other vehicle, take your foot off the accelerator pedal. The vehicle will then return to the preset cruise control speed.

Using Cruise Control on Hills

How well the cruise control will work on hills depends upon your speed, load, and the incline of the hills. When going up steep hills, you may have to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Applying the brake will however, take you out of cruise control. Many drivers find this to be too much trouble and chose not to use cruise control on steep hills.

To Erase Cruise Speed Memory

When you turn off the ignition, operate the cancel switch, or the cruise control ON/OFF switch is turned off, your cruise control set speed memory is erased.

To Disengage Cruise Control

There are three ways to turn off the cruise control.

  1. Step lightly on the brake pedal.
  2. Press the cruise on/off switch to OFF.
  3. Pull the cruise control lever toward the steering wheel to operate the cancel switch.
